Be it known that l.. Cinisrorrinn M. Uni-nei citizen oi tie United.itrrtesfereat Viiansas Cnn@ in the county ot n yanlotte and 'tite ofVKansasi have invented Lerf, and useful lmprove- :ments in d ,i`i'e. .1andi do decla-1a the following e inli, clear. andeXaCt de scription oi'the inveinion snch'as will enabie 1 L, others skilled in the art towhich it Aimpertains to inake anc use the saine. re 'fence ings,

Abeing had to the accompanying drany l Lo theigures oi reierence niarkedthere-- ein which torni part ot this speciiication. This inventionrelates to improvements reinforced concrete ties whereinv new andiniproved structurai features' are combined to support the' usual steelrails on the `road bed, being one ofthe principal objects the inventionto'provide ineans ior supnying the necessary iiezribility in a railroadtrack and strengthening the foundation and anchor-a Le ot thel track onthe road bed.

Another object oi he invention resides in 4 "The rnanner in `which ltorni and place the n forcing' ineinbes so that the tie yis` not onlyrcinrorced thioughout its rigid section nl another object o" theinvention'is to provide a'dnrable mounting for thetrack bolts wherebytheyniay be inserted. and renioved a nnnioer ci times Withoutinjnry tothe apertures in the tie and whereby `the apertures are especiallyreinforced Yfor loca-l strains incident to drawing the track bolts downvery tightly.

it is another obyect of the invention to Construct a tie which inay betaniped with greater ease and'inore securely than those of ordinaryconstruction. n'

TWith these and otherl objects in view I,

have provided the improved details of struc--r tnre which willhereinafter be more tully described and illustrated in .thevacconipanying drawings, wherein:

The rod 25 has an anchor hook 26 tolsecure the end so that anystress exerted by a train rpassing over the track places the rod intension.

The loops 272 are positioned so that when the sections l and Q areplaced together, the

loops Will register to receive a wedge bar which extends through all theloops and has two or more layers of rods, wire inesh, ex-

panded inetal or the like, extends horizon tally throughout the entiretie and supplies additional reinforecement to the overhang ing parts.

The particular method of applying the track bolt which l wish tov useconsists oi casting a vfiat coiled wire arounl the inner `face of thehole Se; and letting the wire project into the hole to .provide threadsinto which the threads on the ltrack bolt may grip and also castingasecond wire 36 of slightly larger diameter around the first, so

that an i local strains caused b i tighteningv .l i e e the bolt tootight will be resisted bythe second wire and prevent the concrete `fromcracking. f

ln placing the ties, the road bed is prepared in the usual manner andthe tie sections setin place and locked by the wedge 27. The liningstrips 8 are then placed in the grooves 1" and the steel rails bolted onthe strips by nieans of the track bolts. lf the rails do not set to theproper gauge, the wedge may he nioved back and forth to per- Init aspread or contraction of the rails and when set, the pins 29 are placedto hold the parts lin position. The ballast is then tainped in so as tolill closely around and under the ribs 4 and llland beneath theshoulders 5, 6, l5 and i6, thereby presenting a wide area for thesubstantial support of the track.

lt is apparent that when the tie is in place, any transverse orlongitudinal movement thereof is resisted by the ballast against thelongitudinal and transverse ribs.

The tie is particuarly applicable for banking around curves as the railon the outer radius ot the curve can be raised and rockA tampedtherebeneath without in any way affecting the strength oi. the tie. i

1What l claini and desire to secure by Letters-Patent is: i

1. A reinforced concrete tie comprising like sections, reinforcing rods'extending through each of said sections, loops on said rods projectingfrom mating ends ot said sections, anda Wedge for joining the loops andconnecting the sections together.

y2. A reinforced concrete tie coinprising like sections, reinforcingrods extending through and anchored in each ot said sections,rectangular loops on said rods projecting froni mating ends of saidsections, a wedge for said loops, and pins for preventing displacementoisaid wedge.

3. A reinforced yconcrete'tie comprising like sections liexiblyconnected together, and a dowel for holding said sections in alignment.

4. A reinitorced concrete tie comprising like sections flexiblyconnected together, a dowel yfor holding the mating ends of saidsections in alignment, and strips for holding adjacent ties Ainalignment.

5.A reinforced concrete tie comprising body portions'forlyin'transversely of a track and integral ineinoers extending from the sidesof the body portions Yfor lying lonH gitudinally with the track. therebeinggrooves extending continuouslythrough the upper faces-.oiI thelongitudinal members and the intermediate body portions and ribsextending' downwardly troni the longitudinal ineinlcers and bodyport-ions, beneath said grooves-and resilient stripsin said groovesextending beyond the ends of the longitudinal members to seat in thegrooves in adjacent ties to Yliorin continuous rail seats.

` 6. In a reintorced concrete tie, a tie section coinprisingalongitudinal portion having a top groove and a base rib, a transverseportionextending` from each side of said longtudinal portion and havinga base rib crossing said first rib, and vreinforcing rods extendingthrough said f longitudinal and transverse portions.

7. A monolithic tie section comprising longitudinal .and transverseportions 'formed finto a cross, base ribs extending along each portionso as to provide shoulders, trussed reinforcing'rods passing througheach portion,.inesh reinforcing passing through the entirev section, andmeans for supporting a rail on said section.

S. ln a reinforced concrete tie, paired body portions 'for lyingtransversely of a track -and each comprising longitudinal members torsupporting a rail, the innerend oil each body portion c having anupwardly facing shelf, reinforcing nienibers in each body portion havingloops extending over the respecrtive shelves and registering with likeloops on reinforcing nieinbers projecting` from the oppositebodyportion, and a connector extending through 'the registering loops.
